step 1, a mobile intelligent terminal collects and stores identification number information of a legal owner of the mobile intelligent terminal, collects human body magnetic field data of the legal owner of the mobile intelligent terminal in real time within a preset time period, constructs a human body magnetic field database of the legal owner within each preset time period, and takes the constructed human body magnetic field database as identification information of the legal owner; the preset time period comprises a first preset time period and a second preset time period, and the first preset time period is 06: 00-18: 00; the second preset time period is 18:00 to 06:00 the next day; because the magnetic field of each human body is different, the human body magnetic field is used as the unique biological characteristic of each human body, and the human body magnetic field can be used as the human body biological characteristic information of identity recognition like finger fingerprints. The intensity of the human body magnetic field data is not constant in each time period, so in this embodiment, two time periods are preset for the human body magnetic field data, that is, the preset time period includes a first preset time period and a second preset time period, and the first preset time period is 06:00 to 18: 00; the second preset time period is 18:00 to 06:00 the next day;

step 2, the mobile intelligent terminal collects body odor data of a legal owner of the mobile intelligent terminal, receives fingerprint information and vein information corresponding to each finger of the legal owner of the mobile intelligent terminal, and constructs a body odor database of the legal owner of the mobile intelligent terminal and a fingerprint information database and a vein information database corresponding to each finger; the mobile intelligent terminal respectively endows a human body magnetic field of a legal owner with a first priority for identity recognition, and the body odor data with a second priority for identity recognition; in identifying whether the operator has a legitimate identity, the first priority has a higher identification confidence than the second priority; the body odor of each person is different, and the body odor data of the person is the same as the biological characteristics of a magnetic field, fingerprints, a face, an iris and the like of the person and also has unique non-replicability, so the body odor data of the person can be used as the characteristic information of identity recognition; regarding the priority problem of the human body magnetic field and the body odor data during identification, for example, when the mobile intelligent terminal judges that the acquired human body magnetic field of the operator belongs to the magnetic field data of the legal owner and judges that the acquired body odor data does not belong to the body odor data of the legal owner, the mobile intelligent terminal judges that the operator is the legal owner;

step 3, the mobile intelligent terminal displays a preset number of payment password input frames to a legal owner on a touch display screen of the mobile intelligent terminal, and each payment password input frame corresponds to seven basic color lists for optional selection; wherein, seven basic colors in the basic color list are respectively red, orange, yellow, green, cyan, blue and purple, and each payment password input box corresponds to a group of payment allowable colors; each group of payment allowable colors is any combination of seven basic colors; for example, the mobile intelligent terminal displays 3 payment password input boxes on a touch display screen of the mobile intelligent terminal, wherein the 3 payment password input boxes are respectively numbered as a 01 input box, a 02 input box and a 03 input box; wherein:

seven basic colors of red, orange, yellow, green, cyan, blue and purple are corresponded in the 01 input box,

the 02 input box is corresponding to seven basic colors of red, orange, yellow, green, cyan, blue and purple,

seven basic colors of red, orange, yellow, green, cyan, blue and purple are correspondingly arranged in the 03 input box;

the basic colors provided in the 3 payment password input boxes are the same, and a legal owner of the mobile intelligent terminal can select at least one basic color in the 01 input box as a group of payment allowable colors corresponding to the 01 input box, for example, red is independently selected as a group of payment allowable colors, or a combination of three basic colors of red, orange and yellow is selected as a group of payment allowable colors corresponding to the 01 input box; similarly, the 02 input box and the 03 input box can be set as required to form corresponding payment permission colors; for example, the set of payment allowance colors corresponding to the 01 input box is red, red and yellow, the set of payment allowance colors corresponding to the 02 input box is orange and yellow, and the set of payment allowance colors corresponding to the 03 input box is blue and purple.

Step 4, according to the basic color list corresponding to each payment password input frame on the touch display screen, a legal owner of the mobile intelligent terminal sequentially selects basic color combinations with custom kinds of numbers to be respectively used as payment allowable colors of each payment password input frame, and the mobile intelligent terminal respectively and correspondingly stores the payment allowable colors corresponding to each payment password input frame; the legal owner of the mobile intelligent terminal correspondingly inputs the integral combination of the payment allowable colors in each payment password input box to form a secondary payment confirmation password of the mobile intelligent terminal for payment; for example, in the 3 payment password input boxes illustrated in step 3, the secondary confirmation payment password of the mobile intelligent terminal is an integral combination of payment allowed colors of each group corresponding to the three input boxes, that is, the secondary confirmation payment password of the mobile intelligent terminal is "red, yellow; orange and yellow; blue, violet ".

In addition, as a safer payment protection method, the secondary confirmation payment password of the mobile intelligent terminal is an integral combination of all payment allowable colors which are sequentially and correspondingly input by a legal owner in each payment password input box according to the sequence; that is to say, the sequence of each basic color also has a limiting effect on the setting of the secondary confirmation payment password, and even if the basic colors selected from each group of payment permission colors are consistent, the authentication of the secondary confirmation payment password by the mobile intelligent terminal cannot be passed as long as the input sequence of the basic colors is not right; for example, the second-time payment confirmation password set by the legal owner of the mobile intelligent terminal is red, red or yellow; orange and yellow; blue and purple, if someone, including the legal owner of the mobile intelligent terminal, the input secondary confirmation payment password is red, yellow and red; orange and yellow; blue and purple, the person still can not pass the safety payment authentication of the mobile intelligent terminal, and the mobile intelligent terminal can not start the payment response, so that the payment password information of the mobile intelligent terminal can be effectively ensured;

because each group of payment permission colors corresponding to each payment password input box is set by the legal owner of the mobile intelligent terminal, and the colors in each group of payment permission colors are randomly set by the legal owner of the mobile intelligent terminal, the final payment permission color is only known by the legal owner of the mobile intelligent terminal, and other people are difficult to guess or crack to obtain the correct payment permission color, so that the safety performance of secondary payment password confirmation of the mobile intelligent terminal is improved, and the authentication accuracy of the mobile intelligent terminal on whether an operator of the mobile intelligent terminal has legal identity is also enhanced;

x is the accumulated sum of the ID card number information, Y is the average value of the ID card number information, and Z is the characteristic value of the ID card number information; x is the number of_iIs an identityThe ith number in the certificate number, m is the number of all numbers in the identity certificate number information; for example, the 18-bit identity card number information of the third legal owner corresponding to the mobile intelligent terminal includes 17-bit numbers and a letter X, and then m in the information is 17; because the identity card number information of each person is unique, the accumulated sum value, the average value of the identity card number information and the feature value of the identity card number information which are obtained by calculation in the step are also unique, so that the obtained corresponding numerical values can be used as the feature value of identity identification, other illegal persons are prevented from forging the identity information, and the payment program of the mobile intelligent terminal is operated in an illegal mode;

For example, the mobile intelligent terminal displays 3 payment password input boxes, which are numbered as a payment password input box number 01, a payment password input box number 02 and a payment password input box number 03, and n is 3; the payment permission colors corresponding to the payment password input box No. 01 are red, red and yellow, the payment permission colors corresponding to the payment password input box No. 02 are orange and yellow, and the payment permission colors corresponding to the payment password input box No. 03 are blue and purple, then J₁That is, the number of the basic colors corresponding to the payment permission colors in the payment password input box No. 01 is 3, I (1,1) is the gray scale value corresponding to the first red basic color in the payment password input box No. 01, I (1,2) is the gray scale value corresponding to the second red basic color in the payment password input box No. 01, I (1,3) is the gray scale value corresponding to the third yellow basic color in the payment password input box No. 01, and the gray scale average value of a group of payment permission colors corresponding to the payment password input box No. 01

Correspondingly, I (2,1) is the gray scale value corresponding to the first orange basic color in the 02-number payment password input box, I (2,2) is the gray scale value corresponding to the yellow basic color in the 02-number payment password input box, and the gray scale average value of a group of payment allowed colors corresponding to the 02-number payment password input boxI (3,1) is in the 03 number payment password input boxThe gray value corresponding to the basic color of the first blue, I (3,2) is the gray value corresponding to the basic color of purple in the No. 03 payment password input box, and the average gray value of a group of payment allowed colors corresponding to the No. 03 payment password input box

n is the number of all payment password input boxes, and I (N) is the gray average value of a group of payment allowable colors corresponding to the nth payment password input box; in combination with the description about the pay password number 01 input box, the pay password number 02 input box and the pay password number 03 input box in the step 5-3, the average value of the gray levels of the pay allowable colors in all the pay password input boxes is

the identity authentication key K in the step is obtained by processing an effective time period, identity card number information of a legal owner of the mobile intelligent terminal and a gray level average value of payment permission colors in all payment password input boxes, the gray level average value of the payment permission colors is uniquely set by the legal owner of the mobile intelligent terminal, the finally obtained identity authentication key K is unique due to the parameters, and if an operator is not the legal owner of the mobile intelligent terminal, the operator is difficult to crack and obtain, so that the identity authentication of the legal person by the mobile intelligent terminal is ensured again, and the payment safety of the mobile intelligent terminal is ensured;
